My old Secretary

I'm Harold 34 and work for the family firm and last year I got a promotion and was sent to the old offices of the firm. They were super ceded, but still used and were going to be upgraded. A brand new building was being built as their replacement, but to some people who worked in the old building the new building was going to be smaller. That started a rumor of staff cutbacks. But they think that the old building wasn't build to house the business housed now and there was a great deal of wasted space. The building would've 3 floors the old had 4, but there 8 to 10 feet between desks. The new building it would be 3feet. Most of all the 4th floor had 2 officers no elevator and most of it empty and it was to hard to take up and bring down stuff if used for storage. Also their was a shed at the back use as storage. The new building would have an elevator, even those it only 3 floors. One of the staff concerned about job cuts was Shirley 58 who is my secretary and sees everything I see and should have realized her job was safe. Shirley is slender short at 5'4" and never married and straight laced I thought on starting working with her. Anyway as the new building started fitting out for us to move into, Shirley thought her days working were numbered. See had seen me reading men's magazines and found one of mature women in my desk drawer. I had bought by mistake. I picked out magazines I wanted put them on top of the mature woman magazine stack and then picked up one to many and paid for them. Only finding out on going thru them later on, but I still read it anyway. Then on a Friday about 2 weeks before we were to move into the new building. Shirley asked me what I was doing on the weekend and I replied same as usual nothing. She left it at that and late in the afternoon not long before we usually finish for the day. She asked me did I want her to come and have some fun together. At first I didn't realize what she meant. I'm not stupid, nor am I a ladies man either. So I asked what of type of fun and she said anything you like I'm up for. I was shocked and also excited and said okay, thinking she will tell me what she was on about. But she then said we could start tonight if you want, I needed time to think it thru and just gave a nod of my head. I still was a little confused by her offer and she left as usual and so did I. I got to my place and had only just got inside, when Shirley pulled up in my driveway and got out carrying a small bag. Shirley came inside and started to get undressed straight away, I might be a ladies man but I do like sex and Shirley looked good to me. We fucked twice that night and bathed together and slept naked together. In the morning I fucked her again and we continued having fun for the rest of the day and night. It's a really free feeling fucking a woman and knowing you can't get her pregnant. No condoms, anyway she finally asked me was her job now safe and me being stupid said safe from what. Dismissal she said, then the penny dropped I said nobody getting fired. Everybody will be still employed in the new building, its smaller because it's built for purpose. She realized I was telling her the truth, but before she could saying I said I've really enjoyed you sleeping with and maybe we can do it again. She thought for moment and said I brought my things for work tomorrow and will stay the night again if you want me too. I said certainly I do and we fucked and had great fun that night and regularly since then. One regret the old office building had more space and there was an old near my office that was empty I could've put a bed in, no such space in the new building. I'm still single and Shirley still my secretary and as of next week my PA. She does the job now but was called a secretary, but with the job name change come a small pay increase 60 dollars and no change to what she does now. I don't travel for my work, but I do go away for fun and Shirley joins me.
